Key Highlights
- The Metis project, which served as Jupiter’s “cornerstone router” since 2021, has launched v7 and become an independent, open-source swap primitive.
- Metis is now defined for builders needing “full control over transaction execution,” including setting custom logic and managing their own RPC.
- This move makes Metis a neutral, community-focused infrastructure tool for the entire Solana ecosystem.
Decentralized finance (DeFi) aggregator Jupiter has announced the launch of Metis v7 and its transition into an independent, standalone project, separating it from the Jupiter ecosystem.
Metis, described by Jupiter as having “long been the cornerstone router” of the Solana network, is now being positioned to operate exclusively as a public good for the broader ecosystem.
The need for Metis’ separation
While Metis was previously provided as a public service since 2021, Jupiter stated that with its platform now powered by the multi-router system Ultra, “it’s the right time for Metis to stand on its own.”
The launch of Metis v7 brings improvements to the engine, such as new routing algorithms, better performance, and integration with over 60 liquidity venues. This v7 release will be the final version managed under Jupiter’s direct umbrella, as the project is formally transitioning to independent public good status.
The separation is seen as necessary for several reasons: Jupiter Ultra now utilizes multiple routers; Metis quotes were being inaccurately labeled as “Jupiter quotes” across the ecosystem; and Jupiter itself has expanded into a complex DeFi super app that requires features beyond what Metis alone provides, such as the Ultra execution engine’s Request for Quote (RFQ) system and multi-router aggregation.
Metis’ development since 2021
Metis has been around since 2021, when Jupiter made its own aggregation engine and made it available to builders through an API and a Binary. Its core function was to facilitate transactions by finding the optimal route plans based on real-time market data.
The technology has improved and now has advanced features like returning raw instruction-level payloads instead of pre-built transactions. It also has “Total Composability,” which lets developers “add custom instructions, change operations, or call Metis from inside any on-chain program (CPI).” It differed from other ecosystem components due to its emphasis on precise regulation.
The difference between Jupiter and Metis
Metis is intended as a low-level, high-control swap primitive. The team gave examples of how it can be used, showing that it is now made for builders who “need full authority” and need to handle their own custom logic, priority fees, slippage, and transaction broadcasting.
This contrasts with Jupiter Ultra, which is intended for users who want the exchange to handle “everything end-to-end,” including automated execution, error handling, maximum sandwich protection, and access to the lowest execution fees available across multiple routing sources. By separating, Metis focuses entirely on catering to these custom, control-intensive use cases.
The v7 update introduces technical capabilities that will drive the independent project’s future utility. These include “Just-in-Time (JIT) aggregation,” which enables the router to compare multiple on-chain Prop AMMs at the moment of execution for the best quote, and “Brent Op Splitting,” a re-engineered algorithm that allows for trade splitting with “hyper-granularity (down to 1 BPS precision) without sacrificing speed.”
Access to the Metis v7 Binary Key will be contingent on a requirement of “10,000 staked JUP” to mitigate spam, and access will be granted only to users with a provided API or Binary Key through the new site. Current Metis Binary integrators have been given a one-month window to migrate to the v7 standard.
The dual announcement of Metis v7 and its independence marks the end of its internal development chapter at Jupiter. The transition hands over a highly capable, low-level routing primitive to the broader building community, reinforcing the ecosystem’s access to specialized tools while allowing Jupiter to focus on its expanded “super app” offerings via its platform.
